Rockfish species vary widely in lifespan. Some even exhibit negligible senescence, showing few signs of aging across the majority of their long life spans. When closely related species have divergent life spans, there is perhaps the opportunity to learn something of how metabolism determines longevity. Accordingly, researchers here report on their study of varied rockfish species, in search of the differences in the molecular biology of cells that lead to differences in life span and pace of aging.

In a new study, researchers compare the genomes of nearly two-thirds of the known species of rockfish that inhabit coastal waters around the Pacific Ocean and uncover some o…
